The Local Ordering of Molten LiNbOa by X-ray Diffraction

LiNbO a crystal has excellent electro-optical and non-linear optical properties [1, 2]. However local fluctuations of the refractive index and light scattering centers prevent a wider application of this material in optical devices. Since sub-grain boundaries seem to cause such inconvenience, the production of sub-grain free LiNbO a crystals is strongly required. Various properties of molten L ...

Diffraction of X-ray Pulse in Crystals

Recently the investigation of the extremely short (subpicosecond) X-ray pulses interaction with crystals takes interest because of the development of linac-driven X-ray Free Electron Laser, operating in the SASE mode and X-ray Volume Free Electron Laser [1, 2]. According to the analysis [3] short X-ray pulse passing through a crystal is accompanied by the significant time delay of radiation. Th...

Hard X ray holographic diffraction imaging.

We determine the absolute electron density of a lithographically grown nanostructure with 25 nm resolution by combining hard x-ray Fourier transform holography with iterative phase retrieval methods. While holography immediately reveals an unambiguous image of the object, we deploy in addition iterative phase retrieval algorithms for pushing the resolution close to the diffraction limit. The us...

[4] X-Ray Diffraction of Protein Crystals

The X-ray study of protein crystals is a difficult and highly specialized field. Eventually, when the structure of a few proteins has been unraveled, the results will be of vital interest to ensytiologists, since they should give information about the spatial arrangement of the “active site” of the enzyme. But meanwhile X-ray methods will have only a secondary interest for enzymologists. The eq...
